Similar to its American big brother Nest, tado wants to revolutionize the smart thermostat market. Ot comes with a minimalistic box, which is placed on the wall. Control takes place almost entirely in tado’s smartphone app. The box on the wall tracks the location of your smartphone and sets temperature according to your location. If you leave home, it turns the temperature down, if you’re on your way home, it turns it up again. Thus tado helps you to make your home as comfortable as possible and cut your energy bill.
